Cloth simulation presets are gone, how do I get them back?
It's probably easier to just tell you what the default presets are:


Cotton: Steps 5, Mass 0.3, Structural 15, Bend 0.5, Spring 5
Denim: Steps 12, Mass 1, Structural 40, Bend 10, Spring 25
Leather: Steps 15, Mass 0.4, Structural 80, Bend 150, Spring 25
Rubber: Steps 7, Mass 3, Structural 15, Bend 25, Spring 25
Silk: Steps 5, Mass 0.15, Structure 5, Bend 0.05, Spring 0


These are as of 2.77.
